If participants chose to use the energy forcing data, they are directed to first use the data listed under 'Observed Energy Forcing Fields' for model simulations.

For those participants who can afford to do so, a) repeat and resubmit their simulations a second time using the NCEP forcing data, and b) characterize differences between the two forcing data sets and how these differences manifest themselves in the model simulations.
